Class NodeModel

  • public class NodeModel
extends java.lang.Object
    Immutable representation of a tree structure accessed through a NodeAdapter.

    A NodeModel instance binds a node with its adapter, providing a uniform way to traverse or compare trees of arbitrary underlying object models.

      • NodeModel

        public NodeModel​(java.lang.Object node,
                 NodeAdapter adapter)
        Creates a new immutable tree with the given root node and adapter.
        Parameters:
        node - the root node of the tree, must not be null
        adapter - the adapter providing access to node types and values, must not be null
        Throws:
        java.lang.NullPointerException - if root or adapter is null
